The slope of the new graph would become steeper.
Slope is the ratio of the increase in the y-coordinates to the increase in x-coordinates of a line or tangent to a curve.
Analysis:
The first equation y = -3x+8 has a gradient = -3 with absolute value = 3
The second equation y = -5x + 8 has a gradient -5, absolute value = 5
The line with the greater steepness is the line with a greater absolute value of the gradient which is y = -5x + 8
